Title: Improvements in or relating to methods of and apparatus for coating wires with metal
Inventor: NORTH PETER JOHN
IPC: B05C11/02
Filed: 1964-02-18
Abstract: <PICT:1030967/C6-C7/1> Apparatus in which a wire is coated with solder by hot dipping comprises an electrically heated molten tin/lead solder bath 1 through which Cu wire W passes over ceramic guide pulleys 4, 5 to a wiping die formed by a parallel hole 7 in a raft 6 of asbestos board floating freely on the surface of the bath. The die ensures a thin concentric coating and the raft prevents oxidation of the molten surface near the wire.  The wire then passes through one or more mist quenching chambers 9 containing water/air spray nozzles, wherein the solder is hardened before the wire passes over a guide pulley 10 to a take up reel.  A plate 15 prevents scum from wire entering the bath collecting under the raft and baffle plates 16 reduce turbulence effects which occur at high wire speeds. The raft may be of graphite and if necessary hollow, alternatively a steel or diamond die may be mounted on a raft. The wire may be acid pickled before coating and aged in steam after coating.  The bath may contain several wire coating arrangements and the entire surface may have a floating cover with apertures for each raft.

Title: Improvements in and relating to Power Transmission Systems.
Inventor: MORRISON WILLIAM
IPC: H02K49/08
Filed: 1916-05-13
Abstract: 100,639. Morrison, W. June 8, 1915, [Convention date]. Electro-magnetic clutches.-In power transmission systems of the type in which a variablespeed engine is connected to the load shaft through a dynamo-electric clutch connected to a battery as described in Specifications 27617/13, 3455/14, and 13176/15, an automatic cut-out is provided which disconnects the battery when the voltage generated by the dynamo clutch becomes less than that of the battery owing to diminished slip between the two rotors. The invention is described in its application to the system set forth in Specification 13176/15, in which the connexions between the battery and the clutch are effected through a controller operated by an electromagnet the circuit of which is controlled from the lever regulating the gas supply to the engine. The controller comprises two armature members A, B carrying contact plates A<1>, A<2>, A<3> and B<1> - - B<6> respectively, to which are secured brush contacts h<6>, k<6>, &c. for engaging with fixed contact bars c<6>, d<6>, &c. The armatures A, B are actuated by electromagnets M, M<1> respectively. The throttle valve n of the engine is actuated from a foot pedal 0 or from a hand-lever P mounted on the steering-wheel of the vehicle. To start up the engine, the throttle valve is opened, preferably by the hand-lever P, and the circuit of the electromagnet M<1> closed through the switch 32. The controller is actuated and connects the battery sections C<1> - - C<4> in series through the contact plates B<1> - - B<6> and the dynamo-electric clutch as a shunt-wound motor. The switch 32 is then opened, and a switch V closed. Further actuation of the hand-lever P or foot-pedal 0 to open the throttle valve n further, closes a switch Q to complete the circuit of the electromagnet M through the switch V. The battery sections and the shunt field windings H<1>, H<2> are now connected in multiple across the armature through the contact plates, A', A<2>, A<3>. The positive pole of the battery is connected to the armature of the clutch through the contacts 63, 64 and a low-resistance coil 61 on the cut-out. A high-resistance coil 60 is connected across the armature brushes. The U-shaped cores of the cut-out are flexibly secured at their upper portions by a resilient steel strip 62. When the current through the coil 61 reverses, the cut-out operates to disconnect the battery from the clutch. In the controller, sparking is prevented at each of the brush contacts by means of auxiliary carbon contacts 19, 20. Resistances r<1>, r<2> are connected in the circuits of the electro-magnets M, M<1> respectively when the armatures A, B are operated. A separate centrifugal clutch, in addition to the centrifugal clutch formed by the brushes and commutator. may be provided as described in Specification 3455/14.

Title: Improvements in or relating to television apparatus
IPC: H04N5/53
Filed: 1956-03-05
Abstract: 805,502. Automatic gain control. GENERAL ELECTRIC CO. Ltd., and BOWN, G. C. S. March 5, 1957 [March 5, 1956], No. 6907/56. Class 40 (5). In a television receiver a synch. separator 7 is fed via condenser 6 from a low-impedance source comprising video stage 4. The complete video waveform (Fig. 2A, not shown) appearing across resistor 8, which is negative-going with the tips of the synch. pulses clamped at earth potential, is applied to the anode of a diode 11. Synch. pulses from the anode of the separator 7 are fed by blocking condenser 12 to an integrating circuit comprising resistors 13, 14 and condenser 15. The waveform across resistor 14, comprising a train of pulses (Fig. 2B, not shown) negative-going from earth potential, is applied to the cathode of diode 11 via a resistor 16 which renders the source impedance high. The cathode potential of diode 11 is zero, save during the first part of each " back-porch " period when the instantaneous potential across resistor 14 is more negative than the black level potential in the waveform applied to the anode. At these periods the cathode potential drops to the black level, so that the cathode potential comprises a train of pulses (Fig. 2C, not shown) of height equal to that of the black level in the video waveform. A diode 17 ensures that this pulse train is entirely negative-going. The pulses are fed to an amplifier 20 via resistor 18 which prevents loading by the amplifier input impedance. and after amplification are rectified by rectifier 25; the smoothed voltage across condenser 29 comprises the A.G.C. potential. A delay is obtained by returning the load resistor 26 to a variable potentiometer 27 across the H.T. supply, and is used as the contrast control.

IPC: B61L1/16
Filed: 1955-03-09
Abstract: 788,453. Railway signals. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 21, 1956 [March 9, 1955], No. 6955/55. Class 105. The passage of a vehicle wheel past a fixed location as in the counting of the number of axles into and out of a railway track section to give an indication when a train has left a section, is detected by a single magnetic structure 4 disposed at one side only of the track rail and having an open magnetic circuit constituting part of an inductive device L having an exciting coil 3 connected in series with an impedance element for energization from an A.C. supply, e.g. 50 p.p.s., the said device L being disposed close to a running rail 1 so that a passing wheel 2 will cut a leakage flux path of the magnetic circuit to produce a temporary change in the effective impedance of the exciting coil, this change being detected for example by the unbalance of a normally balanced impedance bridge in which the series combination is incorporated. As shown, the bridge impedance in series with the exciting coil 3 is preferably a capacitor C and the other two series arms also consist of an inductance L<SP>1</SP> situated out of the influence of the passing wheels and a capacitor C<SP>1</SP>. The capacitor C is such that in the normal conditions, in the absence of a wheel, the inductance of the exciting coil 3 of the capacitor C just does not resonate at the supply frequency but passes through resonance as a wheel passes by. The magnitude of the change, amplified if necessary, actuates a counting device CR of known form. Two such counting devices are operated respectively at the entrance and exit ends of the section of track and the counted outputs compared to indicate whether or not the section has been vacated. To determine the direction of movement of the train, two similar detecting arrangements will be provided with their respective devices L placed along the track a suitable distance apart either on the same or opposite sides of the track and a device provided to indicate which bridge becomes unbalanced first.
